DEVELOPING APPARATUS.

Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed March 23, 1907. Serial N 0. 364,016.

To all whom it may concern:

Be it known that I, GEORGE citizen of the United States of America,residing at-Oklahoma city, in the county of Oklahoma and State ofOklahoma, have invented certain new and useful Improvements inDeveloping Apparatus, of which the following is a specification.

This invention relates to photographing and developing apparatus andparticularly to means for exposing a sensitized film to light and forconducting the same through a series of tanks or compartments for thepurpose of developing and fixing the exposed m. The invention consistsin the details of construction, and in the arrangement and combinationof parts to be hereinafter more fully set forth and claimed.

In describing the invention erence will be had to the accompanyingdrawings forming part of this specification, wherein like charactersdenote corresponding parts in the several views, and in which Figure 1illustrates a top plan view of an apparatus embodying the invention, aportion Of the top being removed to show the parts thereunder in plan;and Fig. 2 illustrates a vertical longitudinal sectional View thereof.

In these drawings A denotes a magazine for containing a roll of film andB a part of the casing through which film is drawn by the rollers C, C,and D denotes the main body of the casing of which the magazine A andchamber B are parts, as shown here in, although the inclosure or casingmay be of any appropriate construction.

Within the casing, I mount two drums E and F so that they are free torotate and I further provide receptacles G and H in O. BEIDLER,

in detail, refwhich the peripheries of the drums extend.

It is intended that the said receptacles G and H shall contain fluidwhich will act on the coated surface of the film and in practice, it isusual to place developing fluid in the receptacle G and fixing fluid inthe re ceptacle H, so that .exposed film is first developed and thenfixed.

A pulley I is mounted to rotate between the drums E and F, whereas apulley J is mounted to rotate near one end of the casing and a pulley Kis mounted to rotate near the opposite end of the casing and thesaidpullevs and the drums have conveying members and wheel T and this thesaid given length may bers R consisting of tapes, bands, cords, chainsor other flexible devices capable of traveling in a circuitous routearound the pulleys and in contact with the peripheries of the drums.Pulleys L and M are also rotatably mounted in the casing and engage theflexible members R constituting guides therefor, is a bracket 0externally of the caslng in which a pulley N these weights hang belowthe flexlble mempull them downwardly so that a uniform tension ismaintained on the several flexible members.

Brushes 1 and 2 are rotatably mounted so as to contact respectively withthe drums E and F, the said brushes being designed for thd purpose ofdislodging films from the drum E and F should such films, by reason of\their moistened condition, have. a tendencly to remain on the drumsafterthe films have traveled beyond the pulley -I or the pulley K. Theshaft of' the brush 1 has a pulley 1 and the shaft of the brush 2 has apulley 2 and these pulleys are connected by a belt 3. The pulley P has apulley a with a crossed belt Q extending from it to a pulley a on theshaft of the brush. The shaft of the pulley P is rotated by a crank Sand hence the pulley a on the shaft of the pulley communicates motion tothe brushes through the pulleys l and 2 and the belt 3 A pulley a isfurthermore mounted on the shaft of the pulley P and a It Q from saidpulley engages the pulley a on the shaft of the pulley J, thus when thepulley P is rotated, the pulley J is positively driven.

The shaft of gear wheel meshes with agear wheel T on one of the therollers are driven to feed the film.

As a means for arresting the crank shaft S at each rotation, I providethe lever V having an arm '0 with a lug o in the path of travel of thesaid crank. The gear wheels and T are in such relation that the feedingrollers will be driven to draw a predetermined length of film, while thecrank handle has been turned once, thus the operator may'know when agiven length of film has en drawn from the magazine so that be proDerlvexrollers C so that.

the pulley P has a gear posed to light. By operating the handle Y, thelug v may move from engagement with the crank and the said crank maythen be free to turn for further operation of the film drawing means andfor the operation of the flexible members constituting the 'con-i veyersso that film may be carried through the receptacles by the drums andconveyers. The pulleys I and K are driven from the pulley P through themedium of two belts E E and pulleys, one of which E is on the shaft ofthe pulley I and the other ,ofwhich E is on the shaft of the pulley K.It follows from what has been said that rotation of the crank S to turnthe pulley P results in driving the pulleys I, J and K, and as theflexible members R engage said pulleys motion is communicated to theflexible members and the flexible members carry the film with thoseportions of the drums that are in the fluid and serve, to effect thedeveloping and fixing of the film, it being shown in the drawing thatthe said film, identified in the drawing by the reference character R,is rg'awn from the magazine by the rollers I claim- 1. In a machinerelating to photography, a casing closed against actinic light incommunication with means for containing a supply of film adapted to bephotographically treated, means for delivering the after exposure fromthe means for containing a supply thereof to the said casing, areceptacle within the casing, a drum in the casing rotatably supportedwith its periphery extending into the receptacle, traveling members 'inthe casing adapted to hold thefilm on the drum While the said drum isro-' tated, and means for rotating the drum and operating the travelingmembers and the means for delivering the film to the casing in unlson.

2. In a machine relating to photography, a magazine for containing aroll of 111, means for delivering and cutting the. portion of the filmexposed from the remainder thereof, receptacles for containing liquid,drums mounted to rotate in the receptacles, a pulley at the rear of thedrums, a pulley at the front of the drums, a pulley between the drums,conveyers running over the pulleys and contacting with the drums, andweights on the conveyers for regulating the tension thereof. a

3. In a machine relating to photography, means for containing a supplyof film, a cas-v ing in communication with the means for containing asupply of film, receptacles within the casing, drums mounted with theirperipheries in the receptacles, means for feeding film from the meansfor containing the film to the casing, pulleys between the drums,traveling members .in the casing adapted to coact with the peripheriesof the for. holding the films incontact with drums, thedrums, the saidtraveling members operating over the pulleys and carrying the film fromone of the drums to the other, and

means for operating the rotatable parts of the device simultaneously.

In testimony whereof I aifix my signature. in the presence of twowitnesses this 15thday of March, 1907.
